First, install Natty on the HD or USB stick of your choice, accepting all the defaults as appropriate.Once you are booted into your new OS install, do these steps in a terminal window, orif you wish and it's easier you can do it from an SSH session.

Code:

Optional First Step (Skip this if you don't care about SSH):Optional 1: Press the upper left 'start' button on the desktop and in the search field enter 'terminal'. Click it and open a terminal window.

In the terminal window, type:

sudo apt-get install openssh-server

This will install the SSH server. Once the server is installed, you can connect to your machine via SSH and perform the rest of the steps listed below.

END Optional First Step

From here on out, the steps should be conducted either in a terminal window or an SSH session.

You should now have a fully functional Ubuntu 11.04 mining rig with Phoenix and poclbm installed. To test it out, you can go into the poclbm directory and run poclbm without any switches and see if your graphics card(s) show up. Do this with:

cd poclbm./poclbm.py

It should list your CPU (possibly) and your graphics cores available.

Here's a couple useful tricks for working with your graphics cards:

To display the temperature of your cores:

aticonfig --odgt --adapter=all

To display the clock speeds of your cores:

aticonfig --odgc --adapter=all

To show or set your fan speed:

Shows fan speedaticonfig --pplib-cmd "get fanspeed 0"

Sets fan speed to 100%aticonfig --pplib-cmd "set fanspeed 0 100"

If you have multiple cores, you'll need to export a different display variable to access the different cores, like this:

Great guide. I just went through all this on my own yesterday before you posted this.

The only major difference with my process for 11.04 (besides running 32-bit) is that I did use the 2.4 AMD ATI SDK, and have seen 5-10% better performance than that shown for my card with the 2.1 SDK on the https://en.bitcoin.it/wiki/Mining_hardware_comparison page. I get 83 Mhash/s, not 78 Mhash/s as shown on the wiki for the ATI 4870.

I tried 2.4 and got about 10% less performance out of 2.4, so I went back to 2.1. The difference you are probably seeing in the guide is the difference between the modern miner and the one the guide was put together with. Your extra hashes are about what you'd see with the BF_INT performance enhancement introduced into the miners recently.

If you're searching these lines for a point, you've probably missed it. There was never anything there in the first place.
